Geant4

Geant4 is a software toolkit used by scientists and engineers to simulate how particles like electrons, photons, or neutrons move and interact with matter. It helps model complex processes such as radiation passing through materials, which is essential in fields like medical imaging, radiation therapy, space exploration, and nuclear research. By accurately predicting particle behavior in different environments, Geant4 allows researchers to design, test, and optimize solutions safely and efficiently, reducing the need for physical experiments and enhancing our understanding of particle interactions in various applications.
